INHALER.

SPECIFICATION forming part of Letters Patent 110.759,885, dated May 17,1904.

Application filed September 14, 1903. Serial No. 173,059. (No model.)

To all whom t concern:

Be it known that I, JOHN Q. A. HAUGnnY, a citizen of the United States,residing at Battlecreek, in the county of Oalhoun and State of Michigan,have invented a new and Improved Inhaler, of which the following is aspeciiication.

My invention relates to medicine-inhalers; and the objects of myimprovements are to provide an instrument in which the air Will passover cotton or other absorbent material, and so become saturated withthe vapors of the medicine it is desired to inhale, to provide aninstrument that can easily be cleaned, and to provide an instrument thatcan be made and sold at a low price. I attain these results by theconstruction illustrated in the accompanying drawings, in which-h Figurel is a view of the inhaler with the cap over the mouthpiece. Fig. 2 is alongitudinal section. Fig. 3 is a cross-section on the line 3 3 oi' Fig.5. Fig. 4 is a cross-section on the line 4 4 of Fig. 2, and Fig. 5 is aview of the mouthpiece.

Similar reference characters refer to like parts throughout the severalviews.

The case l of the inhaler is screw-threaded to receive the mouthpiece 2,which is provided with the end knob 3, the middle collar 4, the threadedcollar 5, having passages 6, and the stem 7, havingI the end shoulder 8.The bore 9 extends through themouthpiece and the stem. Around the stem 7is wrapped the absorbent material l0, which may be absorbent cotton orany other desirable substance. As it is easily removed and replaced, onemedicine can easily be substituted for another. The cap 1l, which isroughened at its outer end, protects the mouthpiece when the inhaler isnot in use and also prevents evaporation oit' the medicine.

When the inhaler is used, the air passes in through passages 6, over theabsorbent material 10, into the chamber l2, and thence through bore 9 tothe mouth. The collar 4 prevents the lips from closing the passages 6.

Having now explained my improvement, what I claim as my invention, anddesire to secure by Letters Patent, isu

l. In an inhaler, the combination of acasing open at one end, amouthpiece fitting into said open end, a stem attached to saidmouthpiece to support absorbent material, said mouthpiece and stemhaving a central bore to permit the air in the casing to be withdrawn,and said mouthpiece having passages to supply air to said casing,substantially as described.

2. In an inhaler, the combination of a cylindrical casing closed at oneend, a mouthpiece having a screw-threaded collar to [it the open end ofthe casing, a stem attached to said mouthpiece to support absorbentmaterial and havingl a shoulder on its ou te r end, said mouthpiece andstem having a central bore to permit air to be withdrawn from thecasing, said threaded collar having passages to supply air to thecasing, and said mouthpiece having a collar to prevent the passagesbeing closed while the inhaler is used, substantially as described.

In testimony whereof I have signed my name to this specilication in thepresence of two subscribing witnesses.
